Hi @Sharon Zhao-MSFT - Your reply is incorrect.
I found this documentation on the Whiteboard support FAQ:
My OneDrive for Business continues to sync the Whiteboard App Data folder. How do I stop it?
When you start a collaboration session, Whiteboard creates a folder in your OneDrive for Business named Whiteboard App Data to store your shared whiteboards. After some collaboration sessions, this folder may continue to sync or process changes indefinitely. You can fix this by choosing to not sync the Whiteboard App Data folder to your device. Disabling sync for this folder won’t limit your ability to use Whiteboard for collaboration sessions.
